' This invention relates to an ignitible stick and a method for makingsuch sticks.

Up-to-date ire making devices comprise, on the one hand, various kindsof mechanical .5 devices such as the well known pocket type of cigar andcigarette lighters, on the other hand, the well known matches are used.The former have the advantage that they can be repeatedly used, but thepurchasing price is relatively high and the construction 1s rathercomplicated and some of their .elements must be repaired often. vTheoperation of these mechanical lighters is not simple and in many typesthe combustible must be renewed from time to time; Matchesare by farpreferred owing lto their simple .manipulation. However, they Vcan beusedibut once and the burnt match forms a troublesome waste product. Thedemand for a re- 20. 'liable instrument for repeatedly producing ire hasnot yet been satisfied. I

The object of the present invention is to provide an ignitible stick forrepeatedly producing fire, combining the simple and .handy manipulationof a match withythe advantage of repeated use of mechanical cigarlighters. The stick for-min thev objectof the invention may be ignite nsuitable surface just asa common match, and

by a persons'breath and then be ignited anew after the flame has beenextinguished. The stick maybenianuf factured so as to ignite either on.any rough surface or only on phosphureted surfaces.

Prior attempts to make matches or v.lighters capable of repeatedignition have failed because they burned too rapidly or were ,soexplosive that special quenching devices were needed. These quenching'ldevices failed to 40 change their dangerous characterv or make the priordevices practical.

The match according to the present invention has for its principalcomponent .a combustible ground mass which is slow burning and leaves nonoteworthy ashy residue. with this ground mass an igniting mass, forexample potassium chlorate and sulphur is used in such amounts thatafter the matchis ignited it may be extinguished by simply blowing uponit. When molded, the combustion lhindering cleavage products.

velocit of the ground mass is lower than that o weakly nitratedcellulose. This ob ject may be attained for example .by using 1n theground mass acetyl cellulose.4 This substance burns more slowly thanweakly nitrated cellulose. With vthis substance are mixed regulatingmaterials such as ammonium oxalate which Vfurther retard the speed ofcombustion since they contain ntrogen yor the like and developcombustion ,3

The whole massof the stick has a sufficient stability to permit ofstriking on ignition surfaces; but the required hardness is not e'ectedby inorganic fillings, kbut by selecting the ground mass and,ifrequ'ired, by organic hardening substances, as the fillings used inconnection with the ordinary ignitiblemass of matches fon' combustionlleavebehind a considerable residue whereby the repeated ignition would.'m impaired or entirely prevented. Theig.- niti'ble stick, according tothe present invention, should preferablyleavebehind no ashes of thiskindgwhich, `for instance, would envelope the end of the stick likeenamel .and '75 would have tofbe removed before the next ignition.Slight ashes, if any, should be by rubbing it on, a/.voluminous so as tobe .easily removable by blowing oi. l

to its composition .the igniti-ble stick 30 consists of.v a. combustibleground mass (the main constituent) an 'initial igniter such .as oxygendeveloping substances together with reduc'ng agents and finallysubstances required for mol-ding the mass, and 'if desired 85 further.substances for retarding the combustion.

Nitrated cellulose,y its derivatives, or other substances havingsimilarqualities such as `acetyl cellulose, adapted for the ground mass. Theremay be added to these ingredientsA materials to regulateftlie rateocombustion, the specific quany t;ityt,ol ,be yadded.:being limited soyas to `give the mass the desired mechanical properties -95 vvandmoldability. Alibiarnples.of such materials are ammomum Oxalate,eamphor, naphfhlene, nitrona A hthalene, lnaphthyl acetate, phenyl, eresornaphthyl .phosphates or carbonates,halides of aromaticdiydrocarbons,.1,90

have proved to be especially acetin, tetramine of hexameth lene etc.either alone or mixed. As oxygen evelo in substances all knownsubstances of this kind may be taken into consideration, such asotassium chlorate, nitrate, bichromate, mmium, lead peroxide, leadnitrate, calcium plumbate and the like. Furthermore 'a number of thecombustibles in common use for making ignitible masses may be employedsuch as sulhur, antimony sulfide, lead thiosulfate. urthermore forincreasing the frictional sensitivity, small quantities of substancessuch as glass powder, pmice-stone, kieselhr, quartz meal mayincorporated into t e mass. If desired, inorganic tillin substances orcoloring matters may be ad ed to a moderate extent. Moreover hardeningsubstances, such as formaldehyde condensation products may be added.

E'amplea lose about 33%, camphor about 3%, sulphur about 6%, potassiumchlorate about 22%, tetramine of hexamethylene about 7%, ammoniumoxalate about 4%, powdered glass about 10%.

(3) In Example 2, further-quantities of acetyl cellulose may besubstituted for nitrocellulose and further quantities of tetramine ofhexamethylene may be substitutedv for camphor.

The ignitible sticks made according to the present invention may bemanufactured in iiferent ways, for instance, in accordance with themethods of Celluloid manufacture. The diiferent additions may be stirredinto a concentrated nitrocellulose solution and the mixture poured intomolds and the solvent evaporated. Care should be taken to avoid theformation of pores which would impair the uniform combustion of thestick. Otherwise the combustion controlling ingredients may beincorporated into the ground mass by kneading` and the mixture may beexpanded to plates by calendering and the plates then cut into suitablepieces. Or a mixture of the components may be prepared and ext-rudedthrough a mouth piece of suitable form so as to obtain bars or rodswhich then are cut into sticks, or the mixture may be molded in presses.

Preferably the ignitible sticks according to the invention are insertedinto metallic sleeves, provided with a feeding device,

similar to those used in pencils with adjustable lead, from whichlsleeve the sticks project but little. After the projecting part is burntoil' or before the stick is reused or after repeated use the unconsumedstick is pushed forward to the desired length. In this way, by excludingvthe lateral access of air, the combustion of the stick beyond apredetermined length is prevented. The closing cap ofthe sleeves may beprovided with a friction surface.

rIhe drawing shows a constructional example of the stick according tothe invention in longitudinal section.

In the drawing, 1 shows an ignitible stick as described above, 2 showsthe metallic sleeve, 3 is a base plate with arms 4 projecting throughslots on opposite sides of the metallic sleeve, by means of which armsthe base plate and thereby the stick can be pushed forward to anydesired length. 6 shows the closing cap of the sleeve, 5 the frictionsurface on the closing cap.

The ignitible sticks may also be used in cigar lighters and similardevices where they would form an advantageous substitute for the usualmechanically operated cigar lighter. If so used their combustionvelocity and consequently also the composition may vary within widelimits. Furthermore the ignitible stick may also be used as a substitutefor solidified alcohol in which case the addition of potassium chloratemay be reduced or entirely dispensedy with.
